Although most evolutionary computation techniques are designed to generate specific solutions to a given instance of a problem, some of these techniques can be explored to solve more generic problems. For instance, while there are many examples of evolutionary algorithms for evolving classification models in data mining or machine learning, the work described in [1] used a genetic programming algorithm to create a generic classification algorithm which will, in turn, generate a specific classification model for any given classification dataset, in any given application domain.

Although the work in [1] consisted of evolving a complete data mining/machine learning algorithm, in the area of optimization this type of approach is named a hyper-heuristic. Hyper-heuristics are search methods that automatically select and combine simpler heuristics, creating a generic heuristic that is used to solve any instance of a given target type of optimization problem. Hence, hyper-heuristics search in the space of heuristics, instead of searching in the problem solution space [2,3], raising the level of generality of the solutions produced by the hyper-heuristic evolutionary algorithm. For instance, a hyper-heuristics can generate a generic heuristics for solving any instance of the traveling salesman problem, involving any number of cities and any set of distances associated with those cities [4]; whilst a conventional evolutionary algorithm would just evolve a solution to one particular instance of the traveling salesman problem, involving a predefined set of cities and associated distances between them.

Whether we name it an approach for automatically designing algorithms or hyper-heuristics, in both cases, a set of human designed procedural components or heuristics surveyed from the literature are chosen as a starting point (or as "building blocks") for the evolutionary search. Besides, new procedural components and heuristics can be automatically generated, depending on which components are first provided to the method.

The main objective of this workshop is to **discuss evolutionary computation methods for generating generic algorithms and/or heuristics.** These methods have the advantage of producing solutions that are applicable to any instance of a problem domain, instead of a solution specifically produced to a single instance of the problem. The areas of application of these methods may include, for instance, data mining, machine learning, and optimization.

Although most evolutionary computation techniques are designed to generate specific solutions to a given instance of a problem, some of these techniques can be explored to solve more generic problems. The main objective of this workshop is to discuss evolutionary computation methods for generating generic algorithms and/or heuristics. These methods have the advantage of producing solutions that are applicable to any instance of a problem domain, instead of a solution specifically produced for a single instance of the problem. The areas of application of these methods may include, for instance, data mining, machine learning, optimization, bioinformatics, image processing, economics, etc.

The workshop welcomes original submissions on all aspects of Evolutionary Computation for Designing Generic Algorithms, which include (but are not limited to) the following topics and themes:

- Evolutionary algorithms for designing generic combinatorial optimization algorithms or heuristics
- Evolutionary algorithms for designing generic machine learning algorithms or heuristics
- Evolutionary algorithms for designing generic function optimization
- Evolutionary algorithms for designing generic algorithms or heuristics for bioinformatics
- (Meta-level) evolutionary algorithms for designing other (base-level) evolutionary algorithms
- Empirical comparison of different hyper-heuristics
- Theoretical analyses of hyper-heuristics
- Automatic selection of algorithms' building blocks as a preprocessing step for the use of hyper-heuristics
- Analysis of the trade-off between generality and effectiveness of different heuristics algorithms or heuristics produced by hyper-heuristics
- Real-world applications of hyper-heuristics
